ADJUSTABLE rLow {AND siiovnn Application filed February 28, 1927. SerialNo. 171,636.

My invention relates to improvements in ad ustable plows and shovels,and it consists in the combinations, constructions, and arrangementshereindescribed and claimed.

An object of my invention is to-provide an adjustable plow and shovelwhich has novel means for holding the'shovel in ad'- justed position yetpermitting the shovel to swing should it strike a stoiieor the like.

A further object of my invention is to provide a device of the typedescribed in, which thenovel adjustment is positioned adjacent theshovel. I I

A further object-of my invention is 'to provide a device of the typedescribed in which the shovel is so shaped that when a plurality ofshovels is used upon a cultivator, they will overlap. v

A further object ofmy. invention 'is-to provide a-device of the typedescribed which will sever weeds or vines of any type, and will not makefurrows as does the ordinary shovel. I

A further object of my invention is to rovide a device of thetypedescribed in which the shovel may be adjustably held in any desiredposition with respect to the surface of the ground.

I Other objects and advantages will appear in the followingspecification, and the novel features of the invention will beparticularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which 7 Figure 1 is a side elevation of thedevice as applied to a shank of a cultivator,

Figure 2 is a plan view of the device,

Figure 3 is asection along the line 33 of Figure 1, and

Figure 4 is a bottom plan view of a portion of the device.

In carrying out my invention, a supporting member will be a shank of a:cultivator, not shown. A body port-ion 2 is provided with an opening 3which is adapted to receive the supporting member 1. Lugs 1 are integralwith the body portion and are adapted to be drawn together by a bolt 5for removably securing I provide the body portion to the supportingmember- The body portion 2 is provided with an integral flange or lipportion .6 having an arcuate-shaped groove 7 in its inner surface. Aclamp Shaving an arcuate-shaped groove 9 within one side thereof isprovided 1 which in actual use the tongue 10 is receivable in the'groove11 and thearcuate-shaped surface 17 is receivable in the arcuate-shapedgroove 9.

The clamp 8: and the bracket 13 are adjust ably secured to the bodyportion 2=by means of a bolt 18 which extends through openings PATENT?witha tongue portion '10 whichis receivable within alongitudinallyextending groovell' in the clamp 8, the head 15, and the flange 6. IFrom the foregoing descriptionof the va I have shown the device in theposition in rious parts of the device,'the operation there I of may bereadily understood. In Figure 1,

which it is best used. The dotted line A I represents the surface of theground. As the device is moved forward in the direction of the arrow B,it is obvious that the shovel 12 for its entire width is disposedbeneaththe ground and will sever all weeds or vines which happen to be in itspath. during the forward movement thereof. If the shovel 12 shouldstrike a stone or other obstacle which could not be moved by'the forwardmovement of the shovel, the friction between the arcuate-shaped surfaces16 and 17 of the head or ball-shaped member 15 and the arcuat-e-shapedgrooves 7 and 9 would be overcome, thus allowing the shovel to swingabout the bolt 18 as a. pivot. The shovel and bracket may readily bereset, i. e., moved into their normal positions by making loose'the bolt18. v

The purpose of Figure 4 is to illustrate how the edges and point of theshovel 12 are kept polished by constant use. This also illustrates thatthe shovel moves in a substantially horizontal plane with respect to thesurface of the ground. During this movement the weeds lllu i or the likemay be more readily severed. Furthermore the shovel may be moved withless energy and more'evenly in comparison with the ordinary type ofshovel.

The adjustment adjacent the shovel makes it possible to move the shovelupwardly about the bolt 18 when the device is not in use. The

adjustment also obviates the need of pegs gated groove therein, meansfor ren'iovably se-.

curing said body portion to said support, a flange having anarcuate-shaped groove in tegral with said body portion, a clamp havingan arcuate-shaped groove therein, a tongue portion integral with saidclamp and receivable in the groove in said body portion, a bracket, ashovel rigidly secured to said bracket, a head portion integral withsaid bracket and having arcuate-shaped walls re ceivable in thearcuate-shaped grooves in said clamp and said flange, and means foradjustably securing said head portion between said clamp and saidflange.

2. A device of the type described comprise ing a support, a body portionarranged to be secured to'said support and having an arcuate shapedgroove therein, a shovel, a bracket see cur-ed to said shovel and havingarcuateshaped Walls, one of which is adapted to be received in thearcuate-shaped groove of said body portion, a clamp having anarcuateshaped groove adapted to receive the other of saidarcuate-shap'ed walls, and means for adjustably securing saidbracket-between said body portion and said clamp JAMES T.
